I'm working with qgis 2.8 (windows).
I am able to generate maps using qgis atlas. But i have a problem with the scale bar.
When i generate atlas with "fix scale" setting (1:35.000 for instance), the scale length changes for each "slide", each exported map.
Could you tell me why?
I hoped to solve the problem using "predefined method". In vain.
Below are two screenshots showing my problem :
